The evolutionary origins of the three major families of chemoreceptors in arthropods—the
odorant receptor (OR), gustatory receptor (GR), and ionotropic receptor (IR) families …

The ability to identify nutrient-rich food and avoid toxic substances is essential for an
animal's survival. Although olfaction and vision contribute to food detection, the gustatory …

The bed bug, Cimex lectularius, has re-established itself as a ubiquitous human
ectoparasite throughout much of the world during the past two decades. This global …

Chemosensory-related gene (CRG) families have been studied extensively in insects, but
their evolutionary history across the Arthropoda had remained relatively unexplored. Here …

Among the many wonders of nature, the sense of smell of the fly Drosophila melanogaster
might seem, at first glance, of esoteric interest. Nevertheless, for over a century, the 'nose'of …

The origin of the insect odorant receptor (OR) gene family has been hypothesized to have
coincided with the evolution of terrestriality in insects. Missbach et al.(2014) suggested that …

Sensory receptors are at the interface between an organism and its environment and thus
represent key sites for biological innovation. Here, we survey major sensory receptor …

Background The western flower thrips, Frankliniella occidentalis (Pergande), is a globally
invasive pest and plant virus vector on a wide array of food, fiber, and ornamental crops. The …

Understanding the birth and diversification of multigene families is a fundamental
evolutionary problem. I argue for the insect chemoreceptor superfamily as an outstanding …

Hyalella azteca is a cryptic species complex of epibenthic amphipods of interest to
ecotoxicology and evolutionary biology. It is the primary crustacean used in North America …
